5. d) 50%

Step-by-step explanation:

We will use percentage change formula to solve our given problems.

1.  The percent of change when the price of a radio changes from $40.00 to $44.00.

Therefore, the price of radio increased by 10% and option b is the correct choice.

2. The percent of change when the price of an oven changes from $450 to $396.

Therefore, the price of oven decreased by 12% and option d is the correct choice.

3. The top player’s scoring average changes from 20 points per game to 24 points per game.

Therefore, the player's scoring average increased by 20% and option a is the correct choice.

4.  At the start of the football season, Jorge weighed 150 pounds. At the end of the season, he weighed 138 pounds.

[\text{Percent change}=\frac{138-150}{150}*100[/tex]

Therefore, the Jorge's weight decreased by 8% and option d is the correct choice.

5. Sara raised her raw score on a math test from 40 to 60.

Therefore, Sara's score on math test increased by 50% and option d is the correct choice.

it is a horizontal line.
